- Standard procedures were used to measure weight, height and body mass index (BMI). Body density was determined with specifications by Jackson & Pollock16 for men ([1,1093800 - 0,0008267 * (sum of skinfolds of the chest, abdomen and thigh) + 0,0000016 * (sum of skinfolds of the chest, abdomen and thigh)2 - 0,0002574 * age]) and Jackson et al.17 for women ([1,0994921 - 0,0009929 * (sum of skinfolds of the triceps, suprailiac and thigh) + 0,0000023 * (sum of skinfolds of the triceps, suprailiac and thigh)2 - 0,0001392 * age]). Body fat percentage was derived from Siri equation ([4.91 / density - 4.5] * 100).
